I’m shooting a 7RM, mostly Nosler brass (sometimes Hornady)

I’ve been shooting the CCI 250 magnums. I’ve had really frightening pressure spikes (for comply inexplicable reasons) on two different rounds, blew the firing pin back into the bolt and ruined it.

No more of that,

What primers SHOULD I be using?

I hunt around 7,500’, 40*, shooting RL26 and absolute hammer 155.

Thanks all
